The new-look Newport Pagnell Post Office will open later this month.
Milton Keynes North MP, Mark Lancaster, will unveil the refurbished building, which has been modernised as a ‘main’ style open-plan branch.
The post office, based in 30-32 High Street, will be officially opened at 11am on Friday, April 26.
Mr Lancaster will cut the ribbon at the event, which will be hosted by subpostmaster Andrew Craddock.
Customers are set to benefit from access to products and services from Monday to Saturday, between 9am and 5.30pm. The new Saturday afternoon opening will mean it is open an extra five hours per week.
